On the other hand, "total omnidirectional sensitivity" refers to the receiving sensitivity of the receiver of the wireless communication device in stereo omnidirectional direction to comprehensively measure the receiver receiving capability of the wireless communication device. The "total omnidirectional sensitivity" test method measures the position of the wireless communication device, and the 0 coordinate and the φ axis of the spherical coordinate are measured at intervals of 3 ,, and the effective omnidirectional receiving sensitivity (mf of the effective omnidirectional receiving sensitivity) is measured. , and all the measured wires are integrated to calculate the "total omnidirectional sensitivity". Therefore, when the designer of the wireless communication device completes the design of the radio (IV), it must measure the radio frequency of the wireless communication device in the three-dimensional microwave darkroom and the "total omnidirectional recording" to evaluate the emission of the device. And receiving ability. Then, based on the measured "total radiated power" and "total omnidirectional sensitivity", the designer can readjust the radio frequency circuit 1 (not shown in Figure 1) to get the maximum "total size" in accordance with the # rail specification. The "power" and the lowest "total omnidirectional sensitivity, however, are so laborious and time consuming. Under limited time and Wei, the best "total radiation power" and "total omnidirectional sensitivity" may not be obtained. For example, please refer to Figures 3 to 6, as described elsewhere, the designer of the line switching device usually assumes that the impedance of all frequency bands is 50 Ω. In fact, 'in order to reduce the size of the antenna and meet the money section The requirements, the impedance of the antenna plus the matching circuit is difficult to access, thus causing difficulty in design. Figures 3 and 4 are Schematic diagram and voltage standing wave ratio diagram of the 1352208 κ-GSM tri-band antenna, 5th Figure 6 and Figure 6 are schematic diagrams of the Smith chart and voltage standing wave ratio of another GSM tri-band antenna. The communication system corresponding to the above two-band is: EGSM900 system, the receiving frequency band is between 925.2 MHz and 959.8 dead, and transmission The frequency band is between 88〇2 MHz and 914 8 MHz' DCS1800 system, the receiving frequency band is between 18〇5 2 MHz and 1879 8 MHz/Η and the transmission band is between 710.2 MHz and 1784.8 MHz; PCS1900 = The receiving band is between 193 megahertz and 199 megahertz, and the transmission band is φ " between 185 〇 赫 丨 and 丨 91 〇 GHz. From the 3 ′′ and 5th, the GSM tri-band antenna The requirement of not being able to connect to the three-bands is such that the designer has no way of knowing that the antenna and its matching circuit can make the active light-radiation characteristics of the wireless communication device to be optimally utilized. [Invention] The law reveals an impedance load characteristic. Adjusting a plurality of service operating frequency bands of a radio frequency circuit, designing a plurality of service fixtures, wherein the plurality of test impedances are in the money domain; and multiplexing the test points to the non-frequency circuit to pass the 1352208; The plurality of fine m scalar singular wireless circuit circuits (four) dodge; according to the complex array radio frequency, determine the radio frequency circuit - the most anti-load area; and adjust the radio frequency circuit according to the optimal impedance negative domain Ben According to another aspect of the invention, an electronic ray of a radio frequency circuit is adjusted by an impedance load characteristic, and the Wei Jia said a fixture, each of which is a test load, an impedance load region of one of the preset operating frequency bands; a test device, through the plural Test fixtures - test fixtures are transferred to one of the test points of the radio frequency circuit for measuring the radio frequency characteristics of the radio frequency circuit through the plurality of test spikes; The test device is configured to determine, according to the RF characteristics of the complex array, the maximum anti-turning domain of the radio frequency to improve the basis of the wireless surface circuit.

Then according to the measured radio frequency characteristics, the best impedance load & field of the ..., > wireless RF circuit, and according to the 5 weeks of the entire radio frequency circuit. 70. When the wireless shooting is completed, the designer can use the process 2, such as: the initial transmission and reception capability of the frequency = road, and adjust the wireless radio frequency to the total amount of the three-dimensional microwave dark feed. The power and total ft design rides the estimated size of the _ _ _ wei and the receiving energy H to adjust the wireless _ road to save the design time and resources of the wireless _ circuit f. In the present month/7|Table 70, 'each test fixture corresponds to the preset operating frequency band: the anti-load area' is used to simulate the antenna load. Therefore, in designing each test.
